The finite difference time domain (FDTD) method is used in this study because it simultaneously solves both sound wave propagation in fluid and elastic wave propagation in solid. The calculated value of sound transmission loss gives good agreement with that of mass law. Sound transmission of saw-shaped wave approximated by the sum of sine waves is also calculated. As a result, it is considered that even if a non-linear sound wave reaches to a thin plate, its high frequency components are reduced and the transmitted wave can be treated as a linear wave under the condition which an incident plane wave transmits to infinitely large thin plate.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064303014","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-08-009","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構"},{"subitem_text_value":"宇宙航空研究開発機構"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"村上, 桂一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青山, 剛史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Murakami, Keiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoyama, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"64303014.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64303014.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5416/files/64303014.pdf"},"version_id":"928db470-84a2-40e5-a490-40dfad747c30"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"FDTD法による音響透過損失の数値解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"FDTD法による音響透過損失の数値解析"}]},"item_type_id":"5","owner":"1","path":["964","1541","1885","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5416","relation_version_is_last":true,"title":["FDTD法による音響透過損失の数値解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:15:26.658170+00:00"}
